The obverse of the coin features the crowned mature head of Queen Elizabeth II facing right (her effigy known as the "Fourth Portrait", by Ian Rank-Broadley). The Queen wears the "Girls of Great Britain and Ireland" diamond tiara, a wedding gift from Queen Mary (Her Majesty's grandmother) in 1947 - which she also has on the Machin and the Gottwald portraits. In small letters below the neck truncation, the designer's initials IRB.
Given that Samoa has been a republic since it gained independence in 1962, it is unclear why the Queen's effigy is displayed on the coin.
Below the portrait, a small Coat of Arms of Samoa. It consists of a shield, the lower two-thirds of which have five stars representing the constellation of the Southern Cross; the upper third depicts a beach and a coconut palm. The shield is surmounted by a cross with rays radiating from its centre, and is superimposed on two concentric circles representing the world, and an olive branch wreath - as in the United Nations Badge. On a ribbon below, the motto FA'AVAE I LE ATUA SAMOA, meaning "God be the Foundation of Samoa".
Around above, the name of the country: SAMOA. Around below left, the date of issue 2022; around below right, the face value HALF DOLLAR.
